This is one of a number of enhancements to Facebook Connect and Facebook's API that the company is expected to announce at F8, its developers conference, in April. All of these features are part of the "Open Graph API" project, designed to encourage people to stay logged into Facebook at all times, and to make Facebook a part of their experience on as many sites as possible.

If this were to take off -- and Facebook Connect is already getting huge -- Facebook would essentially be stamping its brand on the entire web. It would also be in a better position to take on Google with an ad network of its own.
